Unveiling the dark Universe with Neutral Hydrogen

by Dr. Marta Spinelli

H6 (UHG)




The understanding of the role and nature of dark matter and dark energy is the next fundamental question in Cosmology and requires mapping increasingly larger volumes of the observable Universe. The radio SKA Observatory and its precursors will be key to measuring the large-scale distribution of neutral hydrogen opening a new and unique observational window onto the dark Universe. In this talk, I will discuss the timely and innovative subject of Neutral Hydrogen Intensity Mapping and what we hope to achieve once the SKAO is fully operational. Moreover, I will present current results from the available data from the SKAO precursor MeerKAT discussing some of the challenges that these types of measurements have to overcome.
